Data DictionaryPageIndex_Poly represents the bounds of the Snohomish County Assessor’s tax Parcel Maps and is used as the index layer in Esri’s Data Driven Pages tool to automate Parcel Map generation. PageIndex_Poly is maintained as part of the County’s Integrated Land Records database and is based on the Public Land Survey System representing Sections and Quarter Sections. It is derived from the PLSS_Poly dataset and regenerated every few years to keep up with increasing tax parcel density. At the time of generation, Section Maps are converted into Quarter Section Maps when the unstacked (flattened) tax parcel count is greater than or equal to 150 per section.

The Zoning Geo-Datasets for Snohomish County, WA are a generalized representation of county zoning ordinances. The official county zoning maps are on file at the Public Service Counter within the Snohomish County Department of Planning and Development Services, second floor, County Administration East (Drewell) Building, 3000 Rockefeller, Everett, Washington. For more information, call (425) 388-3311. We strongly recommend that you verify the information contained on those official county zoning maps prior to initiating any development activity. These datasets are a graphic representation derived from the Snohomish County Geographic Information System. It does not represent survey accuracy. These data are based on the best available information at the time of creation and modification.

The Public Land Survey System (PLSS) Grid - Line is linework derived from the master coverage of the PLSS maintained by the Assessor's Office. This dataset only contains linework and attribute information for townships, ranges, sections, quarter sections and quarter quarter sections and government lot lines. It is compiled from recorded surveys and plats, coordinates and linework supplied by private surveyors, Snohomish County Public Works Survey, cities, Washington State Department Of Natural Resources (DNR) and the United States Department of the Interior - Bureau of Land Management (BLM). Standard BLM methods are used to construct the aliquot grid. In coastal areas, the aliquot grid may not apply for many of the coastal sections, it has been constructed for the purposes of land title and defining map extents for automated routines.

This data set is a compilation of tax code area boundaries in Snohomish County, Washington. Tax code areas are formed from a composite of special purpose district boundaries such as cities, fire districts, school districts, etc. Tax code areas represent areas with a uniform tax (levy) rate for that area. The boundaries of the present data set are compiled from data sets for many of the taxing districts that were compiled from legal descriptions for each annexation from the original incorporation onward. Legal descriptions were interpreted without assumption of intent or bias from any pre-existing maps. Spatial registration conforms to features in the Snohomish County parcel data set. For areas where special purpose district boundaries have not been converted, the boundaries were taken from a manually maintained atlas.

Preliminary report on the geology of southern Snohomish County, Open File Report 73-1. The map area includes eighty-five square miles in South Snohomish County southeast of Everett, bounded on the west by Interstate 5, on the south by Highway 405 and the Snohomish-King County boundary, on the east and north by the Snohomish River floodplain. The purpose of the project is to provide a geologic map of the area at a scale which can be useful as a tool in urban planning. Since the project has been done in conjunction with the Snohomish County Planning Commission, hopefully, it will provide geologic data that will be useful to them in planning for future metropolitan and industrial growth. The geologic map will provide a basis for applying groundwater, seismic response, slope stability and engineering property studies to the area, all of which are important factors in today's urban and regional planning.
